To all'whom it may concern;

Be it known that I, WALTER P. MURPHY, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented ce1'- tain new and useful Improvements in Metal EndStructures for Railway Cars, of which the following is a specification.

My invention relates to end structures for railwafy cars and has for itsobject to provide a rein orced sheet metal end structure which may bemade relatively light in weight without sacrificing the strength andrigidity required in constructions of this character to resist thestrains due to shifting of the cargo and otherv causes. y

When loading a railway car the heavier parts of the cargo are usuallyplaced in the bottom of the car. In the event of lany shifting of thecargo, such `for example, as is caused by the sudden starting orstopping of the car, the lower part of the car end is subjected togreater strains than the upper portion. One of the specific objects ofthis invention is to provide a novel and inexpensive reinforcing meansfor a corrugated sheet metal car end structure whereby the structurewill be strongest at thepoints where strength is most needed to resistthe severe shocks and strains to which acar end is subjected while inservice.l y

The invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is an4 end view, in elevation, of a sheet metal car end structureconstructed in accordance with the invention;

Fig. 2 is a vertical sectional view taken on line 2--2 of Fig. 1; i

Fig. 3 is a fragmentary sectional viewv taken on line 3-3 of Fig. l;

Fig. 4 is an end view in elevation of a railway car illustrating amodified form of end structure;

Fig. 5 is a vertical section taken on line 5 5 of the structure shown inFig. 41; and

Fig. 6 is a sectional view, taken on the line ve-e of` Fig. e.

Like characters of reference indicate like parts in the several figuresof the drawings. Referring to Figs. 1 to 3 inclusive o f the drawing,the structuretherein shown consists of an upper end sheet 25 formed withAliorizontaatlly disposed contiguous ribs or corrugations 26 whichextend from side to side of the sheet, and lower sheet 27 similarlycorrugated, and side attaching members 28 which are formed withcorrugations 29 adapted to fit over the extremities of the corrugations26 and provided, preferably, with angularly disposed flanges 30 whichoverlap the side sheathing 31 of the car and are se cured to the body bymeans of bolts 32, for example, which pass through the corner posts 33.The upper sheet is preferably formed with a flat upper margin 34 whichis secured by bolts 35 to the end plate 36 of the car. The lower sheetis preferably formed at the bottom with an inturned flange 37 whichextends under the flooring of the car and is secured by means of bolts38 to the end sill 39. rlhe upper sheet overlaps the lower sheet and issecured thereto by rivets 40. The corrugations of the side or attachingmembers 28 fit closely over the corruthe corrugations to the edges ofthe sheetl permits the sheet to be rolled instead of pressed and therebycheapens the manufacture of the end structure, though it will be obviousthat the reinforcing means for the lower part of the car, as will behereinafter described, may be'applied equally well to an end sheet inwhich the corrugations terminate within the edges of the sheet. The sidemembers 28 because of their configuration, have considerable loadbearing strength so that they may serve as load bearing elements. Inthis or analogous constructions in which the attachin'gangles areseparate from the end sheets, it is not necessary to'make the end sheetsconform in width exactly to the width of the car. Any slight variationin the width of diderent cars will be taken care of bythe overlap of theattaching angles on the end sheets. If thick enough metalV is used thewooden corner posts may be disensed with or used simply as nailingstrips. In order to reinforce the lower portion of the end so as towithstand strains incident to the shifting of the cargo and othercauses, I have preferably shown a sheet metal lining 42 which ispreferably riveted to each inwardly projecting corrugation of the lowersheet'27 by rivets 43. The sheet metal lining 42 being secured to thelower end sheet 27 in this manner provides a series of box' girders 44which extend from side to side of the car so as to strengthen andrigidify the end structure at the lower part of the car. The sheet metallining in the construction shown in the drawing extends only part way upthe end, though it will be obvious that the said lining may be extendedhigher up than that illustrated without departing from the invention.

In Figs. 4, 5 and 6, I have shown a modified construction in which theend sheets 45, 46, project beyond the sides of the car. These are formedwith horizontal corrugations 47 which extend to the edges of the sheet,and are secured to the sides of the car by angular attaching members 48which are formed with corrugations 49 adapted to fit the corrugations 47of the sheet. The corrugated portions of the attaching member arepreferably riveted to the sheet by rivets 50 and are secured to the carby means of bolts 51 which extend through the corner posts 52 of thecar.

In these figures I have shown a metal lining 53 which in addition toclosing the corrugations in the end sheet and reinforcing the same, asdescribed in connection with Figs. 1 to 3 inclusive, also provides across brace between the corner posts 52 of the car. This sheet metallining is riveted, as indicated at 54, to the inwardly projectingcorrugations of the end sheet in substantially the same manner asdescribed in connection with Figs. 1 to 3, inclusive, and is providedalong its vertical edges with angular ianges 55 which preferably extendbetween the lining boards 56 and corner` posts 52 of the car. Theseflanges 'are secured to the end posts by means of the bolts 51. Y v
